+ k) RapidIO
+
+ Required properties:
+
+ - device_type : Should be "rapidio"
+ - compatible : Should be "fsl,rapidio-v0.0" or "fsl,rapidio-v1.0"
+ and so on. The version number is got from IP Block Revision
+ Register of RapidIO controller.
+ - #address-cells : Address representation for "rapidio" devices.
+ This field represents the number of cells needed to represent
+ the RapidIO address of the registers. For supporting more than
+ 36-bits RapidIO address, this field should be <2>.
+ - interrupt-parent : the phandle for the interrupt controller that
+ services interrupts for this device.
+ - interrupts : <a b> where a is the interrupt number and b is a
+ field that represents an encoding of the sense and level
+ information for the interrupt.
For this sector, interrupts order should be
+ <err_irq bell_outb_irq bell_inb_irq msg1_tx_irq msg1_rx_irq
+ msg2_tx_irq msg2_rx_irq ... msgN_tx_irq msgN_rx_irq>.
+ #address-cells = <2>;
